To all whom it may concern:

Be it known that I, TOM WILSON, a citi-- zen of the United States,'and aresident of the city of Johnstown, county of Cambria, and State ofPennsylvania, have invented certain new and useful Improvements inRolling-Mill Appliances; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it a pertains to make and use thesame.

iffy invention relates to a rollin mill appliance or apparatus which isa apted to handle blooms and billets which arelapproximately square insection, with or without rounded corners, or slabs which areapproximately rectangular with either square or rounded corners, and myapparatus is adapt- :d to deliver the same to the rolls or receive :hesame from the rolls and turn the pieces on their lon itudinal axes asmay be de """ed for rol mg, reduction or shaping in me difierent groovesof the null rolls.

My invention is particularly applicable to what is known as a two-highmill, which is provided with a pair of reversing rolls provided withapproximately rectangular grooves therein and collars forming part ofthe side boundaries of said grooves, the

rolls being adapted to be moved apart or together to adjust the sizes ofthe different passes in the rolls.

In connection with the rolls 1s a parrot tables, one on each side of themill, which are provided with a plurality of rollers aiilapted to berotated in either direction or to be held stationary as desired, andthese rollers are provided with collars or projections thereon and sospaced apart as to acrolled. In connection with the tables ll alsoprovide a manipulator with an operating portion, which has a series ofserrations or notches formed in the metal bars thereof, which areadapted to be moved upwardly or downwardly preferably by a partialrotation ers they are lifted by the manipulator and supported in theseries of saw-tooth serrations thereof, and as the manipulator islowered, the blooms," billets or slabs contact with the collars orprojections of the table rollers and are turned on their axes as desiredbefore entering the next pass. By reason of this arrangement the variouspasses of the rolls are kept in operation at all times which therebylargely increases the product and reduces the rollingexpense.

Although I refer to use a table with a plurality of ii ting rollershaving grooves therein formed by the collars or otherwise,

I may use a stationary table forming a fixed structure havin projectionsbetween the ro- Figure 2 is a vertical transverse sectional elevationthrough the feed table taken on the line l[l-H of Figure 1; Figure 3 isa detail longitudinal sectional elevation of a portion of the feedtable; Figure 4 is a detail sectional elevation through the movablejoint links; Figure 5 is a detail sectional elevation through thepivoted end of the actuating bar; Figure 6 is a detail view showing oneof the manipulator table rollers in side elevation with the billetsturned a uarter of a revolution to the position shown in Figure 2 andshifted to the next groove in the rollers.

Referring now to the characters of reference on the drawing 1 are thelongitudinal side base frames of the roller feed table upon which thetable rollers 2 are rotatably mounted, 3 are the bevel gears on the endsof the shafts of the table rollers, 41 are the other bevel gears mounted.on the drive shaft 5 adapted to mesh with and. drive the rollers 2 bymeans of the bevel gears 3 mounted thereon, 6 are annular collarsmounted on or forming part of the table rollers forming spaces orgrooves 7, 8, 9 and 10 therebetween; 11, 12, 13 and 14 represent bloomsor billets in various stages of completion and '15 are the serrated ornotched lifting. and lowering members of my manipulator, these beiprovided with notches or serrations 16, 1 18 and 19 in of the actuatingbar and the connecting i the upper surfaces thereof; 20 are spacingmembers secured between the lower portions of the lifting members 15 inorder to maintain them in position and alignment so that they willoperate together in pairs; 21 are the outer portions of the spacers and22 and 23 are openings provided in the lifting members 15 and 20 asillustrated, and adapted to receive the wedges 24, which secure thelifting members 15 to the lower portion of the manipulator construction;25 and 26- are the actuatin bars of the manipulator secured by bolts 27to the member 20, these bolts also being provided with tubular spacinwashers 28 as'illustrated; 29 are pivot b0 ts passing through the endsof the actuating bars 25 and around which they are adapted to bepartially rotated, these bolts being mounted in the castings 30, whichare secured to the channels 33 by means of the flanges 31 and the bolts32 passing there through, while 34: is a longitudinal orizontal channelupon which the channels 33 are mounted; 35 are tie bars mounted on thetops of the channels33-at the side of the casting 30, bracing andconnected to the longitudinal horizontal channels 34 by the bolts 36; 37are pivot bolts pass ng through the movable ends of the actuatlng bars25 and 26, provided with washers or filler blocks 38 between these twomembers, and further provided with links 39 pivoted to the bolts 37, theends of the links 39 being pivotall secured by means of the bolts 40 tothe short rocker arms 41; 53 are longer rocker arms mounted on the rockshaft 42 provided with pivot bolts 43 near the ends of the upper legsthereof; 44 is a pitman pivotally mounted on the bolts 43 and 45; 46 aresmall crank arms mounted on the rotating shaft 47, which shaft is alsorovided with a gear 48 which meshes wit a pinion 52 mounted on the shaft55, which latter shaft 55 has mounted thereon a gear 49 which mesheswith the pinion 50 on the end of the motor shaft of the motor 51; 54 arethe rolls of the rolling mill provided with grooves therein asillustrated and mounted as usual in roll housings 56.

Having thus described my apparatus, I will now describe how it operates:The rolls 54 of the mill receive the bars, blooms, billets or slabs inthe various passes thereof, which are delivered in the direction of andto the feed table and are there received by the rollers 2 thereof withinthe grooves 7, 8, 9 and 10 formed by the collars of said rollers. Afterthe pieces have issued from the mill and it is desired to transfer themto the next pass for further operation, the manipulator is movedupwardly and lifts each of the blooms, billets or slabs between thecollars on the feed table rollers, and after this lifting operation isfinished the manipulator is lowered and as this is done from the lastthe lower surfaces of the blooms, billets or slabs contact with thecollars of the feed table rollers and the pieces are thereby feedrollers in the grooves thereof as shown by the fulllines. Themanipulator bars 15 are then moved upwardly and these blooms or billetsare lifted to the positions shown by the dotted lines, whereupon theyslide down the serrations of the manipulator to the right, whereupon themanipulator is lowered, and as this is done the pieces contact with theupper edges of the collars and are turned substantially ninety 'de eeson their axes and delivered into t e next grooves of the'rollers inposition tobe deivered to the next passes of the rolling mill forfurther reduction.

This process is continuous,

so that larger blooms, billets or or larger passes of the rolling milland .slabs are successively deliveredfto the first are reduced to theirfinal sizes as delivered 1,-

pass thereof. For example, a 7 inch m 8 inch bloom may be rolled to a 4inch w 4 inch billet, this 7 inch x 8 inch bloom entering the table withits 8-inch side resting on the rollers, is transferred and turned ninetydegrees on its axis and edged to enter the 7-inch pass by the saw-toothmanipulator member, which, as it rises, lifts the piece gradually andallows it to slide into or rest in the bottom portion of the serration,and then as the manlpulator is lowered delivers it to the next groove inthe feed rollers, and as this is done the lower surfaces of the piececontact with the upper edges of the collars of the feed rollers, WhlChturn the piece ninety degrees on its axis and delivers it to the nextgroove of the rollers and thence by rotation of the rollers to the mill,into which it is entered for further reduction.

Although I have shown and described my invention in considerable detail,I do not wish to be limited specific details thereof, asshown and de- 1scribed, but may use such modifications in, substitutions for, orequivalents thereof as' are embraced within the scope of myinvention oras pointed out in the claims.

when my manipulator is moved u wardly it lifts the pieces from thetablerol ers and under certain conditions allows the, pieces to S e la yy g v y o the'bottom of to the exact and the serrations, thus Havingthus described my invention, what I c aim and desire to secure byLetters Patent is:
